Know your enemy: the author of Netsky/Sasser speaks

I'm often asked who writes computer viruses. The stereotype is of an antisocial, unathletic male loner sitting in a basement late at night. But Sarah Gordon, virus writer profiler for Symantec Corporation, has written that the typical teenage virus writer is more than likely to be the typical boy next door, with a girlfriend and often on good terms with his parents. There have also been several female virus writers. A recent profile in the New York Times Magazine sheds further light on the once-secret daily lives of a diverse gang of virus writers.
